The formula of calcium chloride is CaCl2, what do those letters and numbers tell you about the compound calcium chloride?
Answer:
It is a compound made up of one Calclum atom and 2 Chloride atoms.
It comes from a synthesis based reaction:
Ca + Cl = CaCL2
The letters you see are the abbreviations of the elements taken from the periodic table of elements.
Explanation:
The formula of calcium chloride is CaCl2, the letters are the symbolic form of chemical compound and numbers are the total number of moles of the chemical compound.
What is a mole?A mole is the single or the smallest form of any chemical compound or element and it can be in any member but the value of one mole will always be equal to the 2.303 × 10²³ of the carbon atom.
In CaCl2, the Ca is the symbol of calcium and Cl is the symbol of chlorine and the 2 Witten after Cl is the total number of moles attached with it which is making the whole chemical.
Therefore, formula of calcium chloride is CaCl2, the letters are the symbolic form of chemical compound and numbers are the total number of moles of the chemical compound.

How did Mendeleev come up with the first periodic table of the elements? (1 point)
A He determined the mass of atoms of each element.
B He estimated the number of electrons in atoms of each element.
C He arranged the elements by different properties to find a pattern.
D He organized the elements by their atomic number.
Mendeleeve's periodic table was based on the atomic mass of each element.
The correct answer is option A: He determined the mass of atoms of each element.
The periodic table can be described as a regular arrangement of elements based on some periodic properties. The periodic table has evolved through the ages. Its patter has been changed several times before it arrived at its present form.
The Mendeleev periodic table was based on the mass of atoms of the elements. This table was published in Russia in 1869. His table even predicted elements that were yet to be discovered.

Why do you think the mass of the carbon atom shown is 12 atomic mass units (amu)?
Answer:
The mass of Carbon-12 is exactly 12 amu. But, that is not the number that is reported in your periodic table. Carbon as it exists in nature is not all carbon-12. There is some small amount of carbon-13 and even traces of carbon-14 in there. The periodic table reports the average mass of the carbon as it is found in nature, not that of pure carbon-12. The average mass of carbon is slightly heaver than carbon-12, because of the slight amounts of those heaver isotopes of carbon in nature.

Rocephin® is an antibiotic sometimes used to treat skin infections. In children, the maximum recommended daily dose of this medicine is 75 mg/kg of body mass. Express this dosage in g/lb, using the conversion 1 kg=2.20 lb.
A daily dose of 75 mg/kg of body mass of Rocephin® is equivalent to 0.034 g/lb of body mass.
In children, the maximum recommended daily dose of this medicine is 75 mg/kg of body mass. First, we will convert this dose to g/kg of body mass using the conversion factor 1 g = 1000 mg.
[tex]\frac{75 mg\ Rocephin}{kg\ body\ mass} \times \frac{1 g\ Rocephin}{1000 mg\ Rocephin} = \frac{0.075 g\ Rocephin }{kg\ body\ mass}[/tex]
Then, we will convert the dose of 0.075 g of Rocephin/kg of body mass to g of Rocephin/lb of body mass using the conversion factor 1 kg = 2.20 lb.
[tex]\frac{0.075 g\ Rocephin }{kg\ body\ mass} \times \frac{1kg\ body\ mass}{2.20lb\ body\ mass} = \frac{0.034 g Rocephin}{lb\ body mass}[/tex]

A pediatrician uses the model above to estimate the height h of a girl, in inches, in terms of the girl's age a, in years. Based on the model, what is the estimated height of a 2-year-old girl?
Answer:
h = 34.2 in
Explanation:
h = 3.0a + 28.2
h = height of a girl.
a = age of a girl.
h = 3.0a + 28.2
h = 3.0(2) + 28.2
h = 6 + 28.2
h = 34.2
The estimated height of a 2-year-old girl is 34.2 in.

If an object at a distance of 6,400 km from the center of the earth weighs 10N, what will be its weight if it is lifted to 12,800 km from the center of the earth? ion:
Answer:
2.5N
Explanation:
since force is inversely proportional to square of the distance apart. that means the ratio of distance apart. so u have 12800×12800÷(6400××6400)=4/1
so the weight will be reduced to 1/4 of 10N
